Large scale cassava starch production line from DOING

Fresh cassava tubers are often used as raw material for starch production. In our design, cassava starch is extracted by physical separation. The procedures are: raw material cleaning and washing, cutting and crushing of cleaned cassava, separating of different contents from starch slurry, concentration of starch slurry, dehydration and drying.

Pre-treatment of raw materials:

After raw cassava tubers are harvested from field, firstly they are cleaned and washed, in case that impurities go into further production and lower quality of finished product.

Processing section:
Cleaned cassava tubers are crushed to make starch released as much as possible. In the crushing section, normally it’s divided into two steps, firstly cassava tubers are cut into small pieces, and secondly small cassava pieces are crushed completely to get cassava mash. In the cassava mash, it contains fiber, protein, fats, starch, water etc. To get purified starch, we need to separate all other contents. Normally solid impurities like fibers and tiny sands are preferentially removed, and then liquid impurities like protein and cell liquid are separated. After all above procedures are finished, we can get refined starch milk.

Drying section
After get refined starch slurry, the next is to remove extra water and get dried starch powder as output product. Firstly dehydration machine can convert starch milk into wet powder with moisture around 40%, and then flash drying machine dry it into powder with moisture 12-14%.
